Answer:
a 90° rotation
I'm not sure about answer...
0.25cm:15m
1cm:60m
1cm:6000 cm
since it is 6.8m apart on the map,
6.8cm: 6000x6.8
=40800cm
=408m
Answer:
Option C
The Area Of Shaded Region is 50.2 cm²
Step-by-step explanation:
For A given Circle,
<u>For</u><u> </u><u>Small</u><u> </u><u>(</u><u>Non-Shaded</u><u>)</u><u> </u><u>Circle</u><u>:</u>
Diameter (d) = 6 cm
Radius = d ÷ 2 = 6/2 = 3 cm
For Area of Small (Non-Shaded) Circle
<h3>
<u>Formula</u><u>:</u></h3>
<u>A = πr²</u>
A = 3.14 × (3)² cm
A = 3.14 × 9 cm
A = 28.26 cm²
<u>For </u><u>A</u><u>r</u><u>e</u><u>a</u><u> </u><u>of</u><u> </u><u>Big</u><u> (</u><u>S</u><u>haded) Circle:</u>
Diameter (d) = 10 cm
Radius = d ÷ 2 = 10/2 = 5 cm
For Area of Small (Non-Shaded) Circle
<h3><u>Formula:</u></h3>
<u>A = πr²</u>
A = 3.14 × (5)² cm
A = 3.14 × 25 cm
A = 78.5 cm²
<u>For</u><u> </u><u>The</u><u> </u><u>Area</u><u> </u><u>Of</u><u> </u><u>Shaded</u><u> </u><u>Region</u>
Area of Big Circle - Area of Small Circle
78.5 cm² - 28.26 cm² = 50.24 cm²
Thus, The Area Of Shaded Region is
50.2 cm²

Answer:
Ganymede: A(sg) = 33.798.589 mil²
Earth´s moon: A(m) = 14.657.448 mil²
Ratio of surface areas : 2,31
Ratio of radio : 1,519
Step-by-step explanation:
We assume, ganymede and the moon both are spheres, according to tha the surface area of a sphere is:
A(s) = 4* π * r² r is radius in each case then we can calculte the surface area for ganymede A(sg) and moon A(m)
A(sg) = 4*3,1416 * (1640)²
A(sg) = 33.798.589 mil²
A(m) = 4*π* (1080)²
A(m) = 4 * 3,1416 * 1166400
A(m) = 14.657.448 mil²
Ratio of surface areas : 33798589/14657448
Ratio of surface areas : 2,31
Ratio of radio : 1640/1080
Ratio of radio : 1,519
